HYDROCARBON-MOTOR.

To all whom it may concern:

Be it known that I, HAROLD D. CHURCH, a citizen of the United States,and resident of Detroit, Wayne county, State of Michigan, have inventedcertain new and useful Improvements in Hydrocarbon-Motors, of which thefollowing'is a specification.

This invention relates to hydrocarbon motors and particularly to thegovernor, the pump, and the throttle and oil valve control.

One of the objects of the invention is to provide a motor with governorcontrolled throttle and oil valves of a particularly simple andeffective construction.

Another object is to provide a novel combination of governor and pumpfor a hydro carbon motor, together with operating means and rconnectionsof novel construction.

Other objects of the invention will appear from the followingdescription taken in connection with the drawings, which form a parthereof, and in which Figure 1 is a side elevation and part section of ahydrocarbon motor embodying the invention; and

Fig. 2 is an enlarged detail sectional view approximately'on the line 22 of Fig. 1.

, eferring to the drawings, 10 represents the base or crank case of ahydrocarbon motor,'upon which the cylinders 11 are suitably mounted. Inaddition to the usual means for lubricating the motor, an auxiliaryoiling device is herein provided for supplying oil to the cylinder wallswhen the motor is started or is operating lunder full load. This meanscomprises a supply pipe 12 which may lead from any suitable pump (notshown) operated by the motor, valve 13, pipe 14, manifold l5 and branchpipes 16,

the latter leading directly to the cylinder walls as shown in Fig. 1.The valve 13 is a progressively opening one and is yieldingly maintainedin closed position by a spring 17 and is operated from the outside ofthe casing by the valve stem or rod 18. Thus the valve 13 is normally inclosed position and itis open for supplying oil tothe walls of thecylinders 11 by longitudinally moving the valve stem or rod 18.

yThe intake manifold 19 of the motor is supplied by a carbureter 20, of`any suitable form, and the quantity of the mixture is controlled as itpasses to the intake manifold by throttles 21 and 22 arranged in tandem.The throttle 21 is manually controlled as Specification of LettersPatent.

by a rod 23 and the throttle 22 is governor controlled as will hereafterappear. The throttle 22 has an arm 24 which is connected to a bell cranklever 25 by a rod 26. The bell crank 25 controls the position of thethrottle 22 and its own position is determined by a rod 27 which isyieldingly pressed toward the left in Fig. 1 by a coil spring 28'adjustable as by the nut 29. The rod 27 extends through the nut 29 andis preferably in axial alinement with the rod 18 of the oil valve 13whereby the position of the rod 27 also determines the position of thevalve 13. Both the rod 27 and the valve stem 18 are spring pressedtoward the left in Fig. 1 so that the tendency of these springs in bothcases is to close their respective valves. An adjusting nut 30 on theend of the rod 27 determines the relative positions of the rods 27 and18. a

There is a casing 31, preferably made in suitable sections forconvenience in assembling, which surrounds the various connections foroperatingy the throttle valve 22, thus supporting and housing saidconnections and preventing tamperingwith their adjustments. Arrangedforwardly of the casing 31 is a water pump 32, the impeller 33 of whichis driven by a shaft 34 which is suitably packed as at .35 and 36 toinsure against leakage. The shaft 34 is supported in a plain bearing 37and an annular ball bearing 38, the latter being arranged ina forwardextension 32 of the casing of the pump 32. Said casing is formed withk aflange 39 by which itis secured to the crank case 10 of the motor. Agear 40 is keyed upon the shaft 34, being arranged 'fordriving thelatter, andis itself driven by the `motor from any suitable gearing,ynot shown.v

It will be seen that the pump impeller 33 is mounted adjacent the rearend of the shaft 34 and upon the forward end of said shaft there is agovernor 41 which comprises ball members 42 pivoted at 43 and arrangedto be drawn yieldingly toward the center of the yshaft by springs 44. j4

For the purpose of communicating the governor action to the remote endof the driving shaftr34, the latter'is made hollow or of tubularL formand a rod 45 passes through and is yadaptedto slide within said shaft34. At its forward end the rod 45 provided with a cross pin 46, shownbest 1n Cri Fig. 2, which pin operates in slots 47 formed in the-shaft34 andis acted upon by yolres 48 on the ball members 42 of the governor.In Fig. l the governor is shown in idle position and it will beunderstood that as the shaft 34 is rotated the ball members 42 will berocked upon their pivots 43, and tlnfough the yokes 48 and pin 4G therod 45 will be moved forwardly.

The rear end of the driving shaft 34 extends from the pump to an opening49 formed in the casing 31 so that this part of the shaft forlns ahousing for the rod 45. The shaft 34 and rod 45 are coaxially arrangedwith the rods Z7 and 18 and the extremefrear end of the rod 45 contactswith the forward end of the rod 27 and thereby determines the positionof the latter rod. It will `be understood that the spring 44 of thegovernor is of sufficient strength to overcome the sln'ings 28 and 17 sothat when the governor is at rest as shown in Fig. l the said springs 28and 17 will be compressed and the throttle 22 and valve 13 will be inopen position. Upon the governor acting as above described, the forwardmovement of the rod 45 permits the springs 28 and 1T to act upon theirrespective valves to partly or wholly close them, depending upon theaction of the governor balls or speed of rotation of the shaft 34. Ifthe motor reaches the maximum speed allowed by the governor with aysmall opening of the throttle valve 22, which it will do of course onlyunder a light load, the valve 13 also will be nearly or perhaps fullyclosed, thus restricting the passage of oil to the cylinder walls 11,but ify the motor requires a fulloijiening of. the throttle to makeitreach its maximum speed, or anything under its maximum, which will ofcourse indicate a full load on the motor, the oil valve 13 will be wideopen and oil will freely pass to the cylinder-,walls to supply the extralubrication needed under those conditions.

It will be understood that the band control and throttleQl is for use incontrolling the motor for speeds below its maximum, the operator havingno power to operate the motorV above the speed at which the governorisset.
